lments will be readily understood from the following description, taken in' connection with the accompanying drawings, in which Figure 1 is a front elevation of a portion ofv a planer equipped With m'y improved system of feed:

Fig., 2a side elevation of the same:

Fig. 3 a diagram of an exemplifying table-actuating system, of gearing:

Fig. 4 an elevation of the "outer face vof the mainv gear-gnard:

Fig. 5 an elevation of the inner face of the'm'ain gear-guard:

Fig. 6 a rear elevation at one end of the rail, the main gear-guardand its contained in Vertical section in the plane of line a Figs. 2, 5 and 7:

Fig. 7 an end view of the rail and the feed-mechanism carried by it, the main gearguard being omitted: and

Fig.. 8a front elevation at the base of one of the housings, showing the reversinggear-box with its cover removed, one of the reversing gears bein` .shown in Vertical section in the plane line a, previously referred to.

A diversity of scales is employed in the drawings. w

In the drawings:-

1, indicates the plener-bed:

2, one of the housingsz' 3, the planer table: i

4, the driving-pulleys:

5, the gears and shafts, considered as a whole, constituting the transmission systen between the driVing-pulleysand the ta e:

6, a selected one of the shafts of the transmission system:

7, a gear fast on this shaft at one side of the planer:

8, the rail:

9, the rail-screws and rod, considered as a group:

10, the 'usual ratchet gears click-boxes on the screWs and rail-rod:

11, a gear mounted at the end of the rail and adapted to ilnpart intermittent rotary motion to the click-boxes:

12, a Vertically splined shaft for transmitting motion to gear 11 from the transmission system of the planert:

13, the base-portion of a side-head:v and '14, the shaft for Operating by hand the elevatin screw of the side-head.

All-o1 the aboVe-mentioned parts, ex'cept as heremafter stated, may be as usual and or so-called are subject to any of the usual modifications of such parts.

Proceeding with the drawings 15, indicates a shaft disposed under and intersecting the axis of splined shaft 12:

6, a pinion on this shaft and engaged by gear 7, the presence of this incident to the fact that shaft imssion system Was selected 6 of the transon account of v its location relative to the front of the housing `and that its rate of turning was lower t 'an was d'esired for the splined shaft: and

1 reversing gearing connecting shaft 15 with the splined shaft.

As usual in planer-feeds, the click-boxes oscillate to predetermined degree immediately'following each reversal of the planer motion, the turning of the click-boxes in one direction being effective upon the feedscrew, and being nefl'ectiv'e when turning in the other direction, the click-box being adjusted, as us'n'al, to select which of its two directions of motion shall' be the effective one. The splined shaft, which is to transmit the motion which is to`ultimat'ely go to outer face of the railgearing beingI the click-box, reverses its direction of continuous turning at each reversal of motion of the planer-table, and, by means of 'the reversing gear 17, the direction of motion of the click-boxrelative to the direction of motion of the plener-feed may be selectively reversed so that the effective motion of the clickbox may be caused to begin either at the 'beginning of the Cutting stroke or at the beginning of the hacking stroke of the table, and this selection may, by means of the reversing gear, be efiected even while the planer is in operation.

Proceeding with the drawings 18, indicates a shaft journaled in the end of the rail parallel with the feed-sorew and projecting from the end of the rail:

19, bevel-gearing connecting shaft 18 with the splined shaft:

20, a friction-disk fast on shaft 18 and forming the driVing-member of an automatic clutch, this disk lying alongside the face of disk 11 previously referred to:

21, a spring Strap clasping the frictiondisk and anchored to gear 11', this strap forming the driven-member of the automatic clutch:

22, a cam-lever carried by gear 11 and cooperating with the strap to serve in releasing its grip when the oam-lever is rocked in either direction:

23, a fixed stop in the path of the camlever and adapted to release the strap and arrest gear 11 when the lever Strikes the stop as the gear turns in one direction 24, an.- adjustable fixed stop in the path of the cam-level' to release the strap and stop the gear as the gear turns in the opposite direction: i

245, an arm pivoted on shaft 18 and carrying the adjustable stop 24 at its end:

25, a fixed emergency stop in the path of the cam-lever beyond the range of adjustment of the adjustable stop away from fixed stop 23:

26, a worm-gear on the hub of arm 24a:

27, ahandled worm engaging this Wormgear and servlng in the angular adjustment of stop 24: 28, a graduated dial on the hub of arm 24a: 29, a casing or main ear-guard removably secured to the end o the rail and serving to inclo'se the clutch and worm-gearand to furnish an outboa'rd bearing for the hub of arm 24- which is loose on shaft 18, this casing also carrying the index coperating with the graduations on the dial: i

30, the clutch-mechanism, etc., at the end of the rail, considered as a whole: and

31, similar mechanism applied to the side head. i

- The friction-disk oscillates in unison with the oscillations of splined shaft 12, and,

While the strap is gripping the friction-disk gency stop and puts Laeeee gear 11 moves with the friction-disk, but the driving grip of the Strap releases and gear 11 comes to rest When the cam-lever strik'es either of the two stops 23 and 24. The oscillations of gear 11 bring about the oscillations of the click-gears, and it follows that, at each reversal of the vtable motion, the click-gears will be turned in a given direction to the 'extent represented by the distance between the two stops. This distance can manifestly be adjusted by turning the worm 27 and this adjustment can be made at any time regardless of whether the planer be in motion or not. The dial indicates the angular position to which stop 24 has been adjusted and it may read in arbitrary numbers or in units of feeding distance.

Fixed stop 25 will obviously never be engaged by the cam-lever in the normal worklng of the mechanism, but if, for any reason, 'casing 29 and arm 24a be removed, and the planer be in motion, stop 25 acts as an emera limit on the turning of gear 11 in lone direction, while stop 23 serves as usual in Stepping the m'otion in the other direction.

The illustrations set forth but one side of the planer, but it is to be understood that in cases of-very wide planers the feedinggmechanism may be duplicated on the other side of the planer, and it will also be understood that the illustration of two feed-screws in the rail is incident to the assumed presence of two saddles on the rail.
